scx_bpf_cid_curr(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

scx_bpf_cid_curr — return the curr task on the CPU at @cid ✨

okay bestie, welcome to the Kernel API Manual page for scx_bpf_cid_curr(9) — yes, the title and the function name are the same, we love a consistent icon. 💅

✨ SYNOPSIS ✨

the whole signature, copied with love and zero edits:

       __bpf_kfunc struct task_struct * scx_bpf_cid_curr (s32 cid , const
       struct bpf_prog_aux *aux );

🎀 ARGUMENTS 🎀

  • cid — cid of interest. literally the cid you're curious about 💅
  • aux — implicit BPF argument to access bpf_prog_aux hidden from BPF progs. it's giving "backstage pass that BPF progs don't get to see" 🎟️

💅 DESCRIPTION 💅

so this is the cid-addressed equivalent of scx_bpf_cpu_curr. that's the vibe. 🦋

⚠️ bestie, this is not a drill: callers must hold the RCU read lock (KF_RCU). like, actually. no cap. 💀

🦋 SEE ALSO 🦋

kernel file: ./kernel/sched/ext/ext.c — and here's the whole squad, no cap:

mwah 💋 — source/version: ./kernel/sched/ext; date: October 2026. that's the whole page, bestie. slay. ✨👑
